The Kidneys Are A Pair Of Organs Located In The Back Of The Abdomen. Each Kidney Is About 4 Or 5 Inches Long -- About The Size Of A Fist. The Kidneys' Function Are To Filter The Blood. All The Blood In Our Bodies Passes Through The Kidneys Several Times A Day. The Kidneys Remove Wastes, Control The Body's Fluid Balance, And Regulate The Balance Of Electrolytes. As The Kidneys Filter Blood, They Create Urine, Which Collects In The Kidneys' Pelvis -- Funnel-Shaped Structures That Drain Down Tubes Called Ureters To The Bladder. Each Kidney Contains Around A Million Units Called Nephrons, Each Of Which Is A Microscopic Filter For Blood. It's Possible To Lose As Much As 90% Of Kidney Function Without Experiencing Any Symptoms Or Problems.
